MOLD FOR CONCRETE FENCE-POSTS.

Specification of L tters Patent.

Patented Sept. 12, 1905.

Application filed pril 28, 1905. Serial No. 257,825.

To all whom it "my concern:

Beitknown that I, JEREMIAH BOLTON, aciti- Zen of the United States, residing at Leslie, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Molds for Concrete Fence-Posts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in molds for making concrete fence-posts; and its object is to provide the same with various new and useful features, hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 is a plan view of a device embodying my invention; Fig. 2, a side elevation of the same; Fig. 3, a transverse section on the line 3 3 of Figs. 1 and 2; Fig. a, the same on the line 4. at of Figs. 1 and 2; Fig. 5, a detail of the plate for inserting the fasteners.

Like numerals refer to like parts in all of the figures.

1 represents any suitable plank or bed-plate on which the post is molded. This plate may be omitted and the post molded on any flat surface, such as a floor or the surface of the ground. 2 represents the sides of the mold, which are preferably divided near the middle and provided with hinges 3. so that they may be folded in more compact form for storage orshipment. Thesesidesarepreferably made of wood and provided with sheet-metal linings 4 to prevent the moisture from penetrating the Wood and warping the same. 5 and 6 are sheet metal partitions extending within grooves in the sides 2 to retain the partitions in place.

7 and 8 are backing-pieces, of wood, to prevent the metal plates from springing under pressure of the contents of the mold.

9 represents loops, preferably of iron rods, the ends of which are joined, forming single screw-threaded portions, on which are nuts 11. These loops connect the sides 2 near the respective ends. In one side and within the loops are pins 12 to limit the separation of the sides. In the loops are wedges 10, engaging one of the sides and forcing the sides toward each other and against the backingpieces 7 and 8. To further hold the sides from spreading, clamps 13 and 14 are provided, which clamps are preferably made of L iron rods bent twice at right angles and arl ranged with the ends inserted within vertical openings 15 in the sides 2. The middle portion of each clamp is elevated above the mold to permit of ready insertion of concrete beneath the clamp. The clamp 13 also being wider than the clamp 14:, when the wedges 10 are removed and the sides separated a proper distance the clamp 13 will go in place of the clamp 1 1 and hold the sides spread apart. The mold can thus be opened out without detachment of the sides from each other and handled more expeditiously than molds which are wholly detached when they are separated from the contents.

The smaller end of the mold is provided with a downwardly-open recess 16, whereby a suitable fence-wire fastening may be inserted in the top of the post through said opening and the mold detached from the post without removing the fastening. To form openings in the post for inserting fastenings or to insert fastenings therein, as occasion may require, I provide a top plate 17, which after the mold is filled is placed on the top of the contents, and in this plate is provided openings 18, through which a rod may be inserted to form openings in the post, or suitable fastenings for the fence-wires may be inserted in the post through said openings.

In operation when the mold has been filled the wedges 10 are removed. The clamps 13 and 14 are also detached. The sides can then be separated and the clamp 13 inserted in place of the clamp 14. The ends of the mold will then be released, and the sides of the mold can be lifted and placed in position for reassembling without further separating the same.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a mold for concrete fence-posts, separable sides, loops connecting the sides, a wedge in each loop, and pins in one side and within the loops.

2-. In a mold for concrete fenceposts, separable sides, loops connecting the sides, nuts on one end of each loop, a wedge in each loop and engaging one of the sides, and a pin in each loop and within one of the sides.

3. In a mold for concrete fence-posts, separable sides, loops connecting the sides, pins and wedges in the loops and clamps inserted in vertical openings in the sides and having their middle portions elevated above the mold.

I. In a mold for concrete fence-posts, separable sides having inner linings and transverse grooves, end plates in the grooves, backingieces to the end plates, and means for clamping the sides against the ends of the backingpieces.

5. In a mold for concrete fence-posts, sides having inner linings and transverse grooves, end plates inserted in the grooves, backingpieces to the end plates, loops connecting the sides, Wedges and pins in the loops and clamps inserted in the vertical openings in the sides.

6. In a mold for concrete fence-posts, sides having vertical grooves and vertical openings, clamps detachably inserted in the openings, end plates detachably inserted in the grooves, loops connecting the sides, Wedges and pins in the loops, and nuts on the loops.

7. In a mold for concrete fence-posts, the combination of sides having inner linings and vertical grooves, and also having vertical ings therein, substantially as and for the purpose specified and means for separating the sides of the molds without detaching the same from each other.

In testimony whereof I aflix my signature in presence of two Witnesses.
